Tooll whom it meg concern:

, Be it known that I, Gnome D. -BEINERT, citizen of the United Statesand resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Lighting-Fixtures, of which the following is a specification. v

My invention relates to lighting fixtures, and more particularly to anarran ement of such fixtures especially designed or use in connectionwith gan work-tables. As is well known, such tab es are usually lightedtables and the like, where it is capable of a by means of electric orother lamps susended above them. This arrangement is,

owever, unsatisfactory in certain classes of work, as for instance, insewin machine requently desirable to bring the lamp much closer to thework, andalso to obtain a greater range of adjustment in directing thelight from thelampf onto the work, than is possible where such lamps aresuspended from overhadi i .1 I

It is one object of the invention, therefore, to provide a lightingfixture secured to the 'table itself, and arranged so as to be widerange of adjustment in all directions.

A fu'rther object of the invention is to so constru'et the various partsof the fixtures as to readily adapt them for use in connec- T separatedto be another. I With the above objects in View, my invention with gangtables formed in sections or units, whereby they may be readilyassembled or disassembled in connection with the table sections orunits, as occasion may require, as for instance, when the table sectionsare moved from one place to tion consists in the construction andarrangement' .of' parts hereinafter described, and 'illustratedin theaccompanying drawings, in which ,7

Figure '1 is a side elevation of a work table with my improved fixturesapplied thereto. Fig. 2 is a transverse section thereof. Fig. 3 is anend elevation on an enlarged scale of one of the junction boxesemployed; and, Fig. 4 is a front elevation of one of said boxes with thecover portion removed.

Referring to the drawings in detail in which I have illustrated, by wayof example, my invention as applied to sewing machine tables such as areused in factories, 1 desig- In Fig. 1, 2 designates the division linevbetween two such adjacent sections, such division preferably beingspanned by one of the brackets 3 which support the table. These bracketsmay be adjustably secured to frames 4 in which may be journaled thepower shaft 5 carrying the belt wheels 6 over which run belts 7 to thewheels 80f the various sewing or other machines supported on thework-tables. As clearly shown in Fig. 2, these tables may and preferablydo consists of two horizontal portions arranged to accommodate two rowsof 0 erators, and having between the horizonta l portions a work trough9, serving to receive and support the work coming from the machine.

,Around the'edge of the horizontal portions of the table, and preferablyalong the inside thereof adjacent the work trough, I arrange a pipe orconduit 10 having at intervals therein junction boxes 11, so locatedthat there is one junction box provided adjacent each machine oroperators posi tion.

Extending upwardly from eaeh f'unction box and supported thereby, is ahol ow post 12, in which slides a standard 13 which maybe clamped in anydesired position by means of a set screw 13. To this standard 13 issocured abracket having a flexible arm 14,

supporting at its end anelectric lamp 15, covered by a half-shade 16. Itw1ll thus be seen that the lamps 15 may be adjusted to or to themachine, or may be lifted up entirely out of the way as circumstancesmay require. p

Referring more particularly to Flgs'. 3

and 4, in which I have shown the details of;

my improved junction box, it will be seen that the box comprises a bodyportlon 11 and a cover portion 21.

preferably fit together on diagonal lines, as

shown at 22 in Fig. 3, and the box is provided at each ,end with socketsl7 having pairs of opposed flanges 20 formed, one on the body pertion,and one on the cover portion, and held together by means of bolts orscrews 20. These sockets are adapted to receive the ends of the pipe orconduit These portions any desired position relative to the work,

sections 10, on the ends of which are screwthreaded collars 19, whichabut a ainst an and inside of said boxes are connected with strips orplates 25 secured to a block of insulation 26. Branch conductors 27extend from the strips 25 up through the socket 18 and post 12 and intothe lamp bracket, and through the flexible arm 14. In order to allow forthe vertical adjustment of the lamp standard and bracket, it

is necessary that the leads 27 be made fiex-' ible and that considerableslack be provided, as indicated at 28. WVith the arrangement abovedescribed, therefore, it will be seen that each table section or unithas its own lighting fixturessecured thereto, and that when it isdesired to remove a unit from or add a unit to the table, or otherwisechange or move said units about, this may be readily accomplished byconnecting or disconnecting any pipe section from the correspondingjunction box, and also connecting or disconnecting the wires 24 and thestrips 25 of the corresponding box. This is a great advantage over theformer practice of wiring the work room and suspending the desired lampsabove the work-tables, for the reason that with my arrangement only asmany lamps are in circuit as are actually required for the number ofmachines or operators at work, and furthermore the lamps can be adjustedso as to much more effectively light the work. It is thought, therefore,that the great advantages of my arrangement will be readily appreciatedby those skilled in the art.

What I claim is 1. The combination with a work table made upofindependent units set end to end, of junction boxes having removablecovers fastened to one edge of each unit, two-part alined socketsprojecting from opposite sides of said junction box, one part of eachsocket being formed on the junction box cover, a lamp bracket supportedby each junction box, and a conduit for electric .wires formed of aplurality of pipe sections extending between the junction boxes andsupported by the divided sockets so that the number of units comprisingsaid work table may be altered without removing the junction boxes.

2. The combination with a pair of parallel work tables and a worksupporting trough between them, of a series of junction boxes secured tothe edges of said tables above said trough, a lamp bracket supported oneach junction box, and a conduit for electric wires formed of aplurality of pipe sections extending between the junction boxes of eachtable, and a section connecting the two conduits 3. A junction boxcomprising a body and a cover (portion, sockets at each end of said box,sai sockets being formed partly on the body and partly on the coverportionof the box, flanges on both sections of each socket to receivescrews for fastening the cover on the box, pipe sections carryingelectric wires having their ends fitted in such sockets, insulatedplates secured in said box to which said wires are removably connected,another socket on the top of said box and formed wholly in the bodyportion thereof, such socket being adapted to receive a lamp supportstandard and wires forming a shunt circuit connected to said in sulatedplates.

Signed at New York, in the county of New York, and State of New York,this 7th day of December, A. D. 1908.
